Good point. That's my mantra as well. We can always caveat things to the nth degree, but at the end of the day, good food must be available. How do we define available? It's easily purchased or acquired, it is reasonably priced, and it provides nutrient density over other foods. If I can only purchase beef that was grain fed, I do not hesitate. To argue that it's inferior to grass fed becomes moot when people can't acquire beef due to price or availability or both. In a perfect world, we'd all have grass-fed meats at reasonable prices. Haven't encountered that world yet. This is one of the points that Dr. Westman makes to people who can benefit by consumption of nutrient dense foods, but are hesitant due to the meat not being from grass-fed, free range animals.
